I think you mean "why should a module calls register_module_init", and I
agree that with this patch a module will not call register_module_init.

But a module is still using the module_init macro.

With this patch, a module will not be able to use the module_init macro
twice.  I am not sure this is an acceptable limitation, especially if we
do not have a dependency system within modules and/or load them with
